vINSTRUIVIENT FOR ATTACHING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 256,297, dated April 11, 1882. Application filed January 26, 1682. (No model.) l

T o all whom itmcoy concern Be it known that I, JASPER W. DAVIS, of Detroit,in the county ot' Wayne and State of Michigan, have invented new and useful Improvements in Setting-Instruments for Attaching Buttons to Garments; and I hereby declare that the following is a full,clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

The nature of this invention relates to certain new and useful improvements in the construction ot' a device for securing buttons to garments, and especially relates vto the construction of the devices for holding the button during the process of securing` the button; and the invention consists in the peculiar construction and combinations ofthe various parts, alll in the usual manner.

E represents a plate which I secure to the inner face of the jaw A, the outer front edge of said platebeing provided with a grooved lip, a. To the upperand outer face of thejaw A, I secure a spring, G, the free end of which projects down over the end ot' thejaw.

The construction thus far described is substantially the same as is set forth in Letters Patent No. 247,032, of September 13,'1881, issued to Farnsworth and Barnes, and upon which my invention is designed as an improvement, and which I will now proceed to describe.

D represents a plate designed to be interposed between the plate E and its jaw. The outer front edge of this plate D is centrally recessed, forming two lips, b, which are bent downward over the edge of the plate E, upon each side of the lip a.

In practice the head ofthe button is inserted beneath the end of the spring` C, the eye of the button entering the recess ot' the plate D and between the lips b thereof, while the ,lip a of 5o the plate E enters said eye. A proper tack, d, With a malleable pointis then inserted. through the material to which the button is to be attached, and Ait is then inserted between the jaws, so that the point of the tack will come immediately under the recess in the lip a. By then compressing thejaws together the point of thc tack is forced through the eye of the button and clinched, while the lips ofthe plate D form rests or stops against which the button is held by the action of the spring G.

In the patent to Farnsworth and Barnes, already referred to, the'jaw is provided with a recess or cut-away portion large enough to allow the button to closely approach and rest against the clinching-plate, which being round does not form a firm base'to support the button. My invention differs from this construction in the use oftwo lips arranged atan angle to thejaw and" constructed to project beyond and over the clinching-plate, and to form a fiat base against which the button is pushed with a direct pressure by the holding-spring;

From the above it will be seen that the lips by being arranged at an angle to thejaw assume positions parallel with the end of the holding-spring when the button is in position, thereby firmly holding the button without danger of its slipping out when the fastening-tackr is being clinched through its shank.

In an instrument for attachingbuttons, the combination, with thejaws A B, the clinchingplate E, and the springf'G, of the plate D, provided w'ith lips b b, bent atan angle to the jaw to form a firm and iiat base for supporting the button, substantially as set forth.

JASPER WV. DAVIS.
